unrepost

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes beyond annotations by stating the action deletes the record owned by the authenticated user, undoes a previous repost, is irreversible, requires authentication, and is rate-limited. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Multiple sentences but all are necessary and informative. Front-loaded with purpose, succinctly covers usage, behavior, and constraints without redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given output schema exists, no need to explain return values. Tool has single parameter, annotations provide safety hints, and description covers purpose, usage, behavioral effects, and alternatives. Complete for decision-making.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Single parameter 'repostUri' with schema description already providing full meaning. Description does not add extra parameter-level details beyond schema, so baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states it 'Remove a repost on AT Protocol' and explains it deletes the repost record. Distinguishes from sibling tool 'repost' by explicitly contrasting creation vs removal.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says use 'repost' to create a repost and this tool only to remove one. Also mentions it undoes a plain repost and cannot be undone without re-calling repost, plus authentication requirement.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
